Antennas & RF interfaces
Consider the antenna, feed, connection and installation environment as one interface.
The installation matters as much as the interface.
An antenna brief needs more than a frequency or a shape. Equipment size, orientation, cable length, connectors and surrounding structures inform the selection. Start with the intended installation, then define the electrical and mechanical interfaces.
What to clarify in the brief
| Installation | Indoor or outdoor use, fixed or mobile installation, mounting location and nearby metalwork. |
|---|---|
| Band and signal path | Target operating band, receive/transmit purpose, coverage direction and equipment interface. |
| Connection and feed | Connector type, cable length, routing and impedance-matching requirements. |
| Mechanical fit and verification | Size limits, mounting method, cable strain and the checks required. |
Define the deliverables
Selection brief
Match the antenna, feed and interface to the intended use, with selection criteria and any items requiring verification.
Installation interfaces
Document the mounting location, mechanical constraints, interface orientation and handover requirements.
Before you start
Can an antenna be selected by appearance alone?
Appearance can guide mechanical discussions, but the operating band, installation and connected equipment still need to be specified. Selection is confirmed against the project requirements.
Let’s define your next project.
Start with the application, existing equipment and critical interfaces.
